I enjoy the artistry. In addition, the flower pots and bonsai planted with ornamental plants are placed indoors and outdoors for viewing.

[0003]

[Problems to be Solved by the Invention] By the way, in a normal vase, Kenzan is simply left in the vase,
If you want to see fresh flowers from different directions, you need to move the vase, or the viewer must move your face or move around the vase to change the viewpoint. However, even if the vase is moved, it is considerably heavy in the case of a large vase,
It is not easy to move, it is troublesome to move it, and it is good if the viewer can move around the vase, but without that space, it does not remain. Such a problem also applies to viewing potted plants, bonsai trees, and the like.

Further, for example, underwater cameras and underwater glasses are
Although the display effect is enhanced when it is displayed in the water for its original purpose, the back side of the product is often difficult to see if the product is simply left in the water, and the entire product is difficult to see. It is preferable to make it visible to customers. Therefore, in view of the above problems, it is an object of the present invention to provide means for rotating an article that is convenient to rotate, such as Kenzan, bonsai, underwater flowers, and underwater camera.

[0005]

The above objects are achieved by the rotating device of the present invention. This rotating device has a case,
A rotating object arranging means for rotatably protruding from the inside of the case to the outside of the case upper surface and arranging an object to be rotated, and a liquid-proof means for protruding the rotating object arranging means to the outside of the case upper surface in a liquid-proof manner. And drive means arranged in the case for rotationally driving the rotated object placement means, and a power supply for operating the drive means.

[0006]

In this rotating device, the object to be rotated is placed on the object to be rotated in advance and the drive means is operated, whereby the object to be rotated is rotated, and the object is rotated accordingly. . Further, since the rotated object placement means is provided on the outside of the upper surface of the case by the liquid-proof means so as to project from the liquid, the liquid (water, etc.) does not enter the case, and the drive means and the power source inside the case are liquid-proof. Protected from.

Therefore, for example, if the rotating device is arranged in a vase containing water and the sword mountain is placed on the object-to-be-rotated arrangement means, as the object-to-be-rotated arrangement rotates in water, the sword mountain, that is, Flowers and tree branches rotate, allowing you to view live flowers from all directions while you are at home. Similarly, when displaying an underwater camera or the like, it is possible to arrange the rotating device in the aquarium, and place the underwater camera on the object to be rotated to display the rotating device.

Further, by providing the reverse rotation preventing means,
If it is intentionally stopped or reversely rotated while the object to be rotated arrangement is rotating, the object to be rotated arrangement is separated from the drive system on the drive means side by the reverse rotation prevention means, and the reverse rotation force is generated. Is not transmitted to the drive system on the drive means side, and damage to the drive system of the drive means is prevented. The object to be rotated arranged on the object-to-be-rotated means may be a sword mountain, a bonsai tree, a flowerpot, or a cup for putting water. Any article that is convenient to rotate in water, such as underwater glasses, may be used.

EXAMPLES The rotating device of the present invention will be described below based on examples. 1 is a cross-sectional view of a main part of a rotating device according to an embodiment.
Shown in This rotating device includes a case 1 including a case body 1a and a back cover 1b that is detachably attached to the bottom of the case body 1a and screwed to a liquid proof. A gear 3 is attached to a rotating shaft 2a of a motor (driving means) 2 arranged in the case 1, and another gear 4 having a larger diameter than the gear 3 is meshed with the gear 3 so that the gear 4 has a shaft 5a. Installed on.
The gears 3 and 4 are arranged in a gear box 6 fixed on the motor 2, and the upper end of the shaft 5 projects from the upper surface of the gear box 6.

Immediately above the shaft 5, there is rotatably arranged a connecting shaft 7 whose upper end projects outside the upper surface of the case 1 and whose lower end faces the upper end of the shaft 5. The upper end of the shaft 5 is
It is attached by a screw 9 to a clutch 8 provided on the outer periphery of the upper end portion and the lower end portion of the connecting shaft 7, and the shaft 5 and the connecting shaft 7 are integrally connected via the clutch 8. Therefore, the rotation of the motor 2 is transmitted from the shaft 5 through the gears 3 and 4 to the connecting shaft 7 through the clutch 8.

An oil sealer (liquid-proof means) 10 for preventing water from entering the case 1 is provided at a portion where the connecting shaft 7 penetrates the upper surface of the case 1. A turntable 11 is fixed to the upper end of the connecting shaft 7 with screws 12 so as to rotate integrally with the connecting shaft 7. In this embodiment, the gears 3 and 4 and the shaft 5 form a drive system for the motor 2, and the connecting shaft 7, the clutch 8 and the turntable 11 form a rotated object placement means.

Here, it is necessary to properly select the gear ratio of the gears 3 and 4 and the rotation speed of the motor 2. This is because it is not necessary to rotate the turntable 11 so fast for appreciation of bonsai, fresh flowers, etc., or for display of an underwater camera, etc., and the turntable 11 rotates about 1 to 5 revolutions /
Minutes are preferred, with rotation of 90 to 100 seconds being most preferred. Therefore, the gear ratio of the gears 3 and 4 is adjusted or the rotation speed of the motor 2 is controlled accordingly.

Also, in this embodiment, the turntable 11
The reverse rotation preventing means 13 for coping with the case where the rotation is intentionally stopped during the rotation of the
It is provided in. This reverse rotation preventing means 13 is shown in an enlarged manner in FIG. Here, a recess 7a provided around the lower end of the connecting shaft 7, a steel ball 14 fitted in the recess 7a, a coil spring 15 for pressing the steel ball 14 against the recess 7a, and a steel ball 14 are provided.
The reverse rotation preventing means 13 is composed of the screw screw 16 for stopping the coil spring 15.

That is, when the turntable 11 is rotating in the forward direction, the shaft 5, the connecting shaft 7 and the clutch 8 rotate integrally, but the rotation of the turntable 11 may be stopped or the rotating direction may be reversed. In such a case, since the rotational force in the reverse direction is applied to the connecting shaft 7, the connecting shaft 7 resists the rotational force in the positive direction received through the clutch 8 and the coil spring 15.
The steel ball 14 urged by is rolling in the concave portion 7a and rotating in the opposite direction. Therefore, the reverse rotation is absorbed by the clutch 8 and is not transmitted to the shaft 5, so that the gears 3 and 4 can be prevented from being damaged.

A battery (dry cell or the like) 20 as a power source of the motor 2 is arranged in the case 1, and the battery 2
A battery cover 21 is detachably attached to the side surface of the case body 1a to prevent the entry and exit of 0. Further, the motor 2 is turned on / off on the side surface of the case body 1a.
A switch 22 for F is provided on the liquid proof. The motor 2, the battery 20, and the switch 22 are wired as shown.

In the rotating device configured as described above, for example, a bonsai tree, a flowerpot, a vase, or the like is placed on the turntable 11. Then, when the switch 22 is turned on, the motor 2 operates, and the rotation of the motor 2 is transmitted to the turntable 11 through the gears 3, 4, the shaft 5, the clutch 8 and the connecting shaft 7, and the rotation of the turntable 11 causes The object placed on the turntable 11 rotates. Therefore, the bonsai tree, the flowerpot, the vase, etc. can be viewed in all directions while being at home. Of course, even if the turntable 11 is intentionally rotated in the reverse direction during the rotation in the normal direction, the reverse rotation preventing means 13 causes the connecting shaft 7 to idle, and in reverse rotation, the gears 3 and 4 are connected. It is not transmitted to the shaft 5.

If the rotating device is placed in the water of the vase and the sword mountain is placed on the turntable 11, the fresh flowers stabbed on the sword mountain can be rotated. If the underwater camera is placed on 11 and rotated, the underwater camera can be made to look good to the customer while rotating underwater camera, and the display effect is enhanced. Alternatively, the algae can be slowly rotated in a tropical fish tank. Of course, since the rotating device has a liquid-proof structure, water does not enter the case 1.

FIG. 3 is a partial sectional view of a main part of a rotating device according to another embodiment. However, FIG. 3 shows only the parts different from the embodiment of FIG. 1, and the other parts have the same structure as FIG. In this embodiment, the shaft 35 to which the gear 4 is attached is fitted into the clutch 38, and the turntable 31 is directly attached to the clutch 38 with the screw 32. Further, the clutch 38 is provided with the reverse rotation preventing means 33 having the same structure as that described above.

At a portion where the shaft 35 penetrates the upper surface of the case 1, an oil sealer mounting bracket 40 is fixed by a nut 41, and between the oil sealer mounting bracket 40 and the outer surface of the case 1 and between the nut 41 and the case 1. Between the inside of
Each packing 42 is interposed. Further, the oil sealer mounting bracket 40 is provided with an oil sealer 43. In this embodiment, the packing 42 and the oil sealer 43 constitute a liquid-proof means, and the turntable 3
1 and the clutch 38 constitute a rotated object placement means.

Also in this rotating device, a bonsai tree, a vase, an underwater flower, an underwater camera, etc. can be placed on the turntable 31 and rotated as in the above. When the turntable 31 is rotated in the reverse direction, the reverse rotation preventing means 33 idles the clutch 38, and the reverse rotation is not transmitted to the shaft 35. FIG. 4 shows a modification of FIG. In FIG. 1, the battery cover 21 is detachably fitted to the side surface of the case body 1a, and the switch 22 is provided so as to project from the side surface of the case body 1a. An electromagnetic switch 23, which is known as a switch, is attached to the inner surface of the case body 1a. By doing so, the liquid-proof structure for the battery cover 21 and the switch 23 becomes unnecessary, and the case 1 can be more surely made to have the liquid-proof structure. Of course, the operation of the electromagnetic switch 23 can be performed from outside the case 1, and the battery 20 can be replaced by removing the back cover 1b.

In each of the above embodiments, a turntable is used as the rotating object placement means, but as shown in FIG. 5, the sword mountain 50 itself may be used. In this case, an adapter 51 is screwed onto the lower part of the sword mountain 50, and the adapter 51 serves as the connecting shaft 7 shown in FIGS.
